Management of the stresses in CWR on the bridge

Abstract

Railway bridges have to ensure the same traffic safety and ride comfort along the entire length of the railway line including track sections on the bridges. Authors investigated the possibilities to avoid rail expansion joints in track on the bridge, in order to provide required traffic safety, as well as ride comfort on the railway bridges. This approach contributes to the reduction of maintenance costs and adverse environmental impact (noise and vibration). The original algorithm for reducing the rail stresses due to the vehicle/track/bridge interaction was presented in this paper.
